Abstract
The utility model discloses a nonmetal compressibility testing clamp comprising a base and a clamping board for clamping samples. The base is provided with an L-shaped step with two planes vertical with each other, the clamping board for clamping samples is screw down on the vertical plane of the base step, and one side surface of the base is installed with a positioning block for assuring that a sample is clamped in alignment. According to the utility model, a sampled is positioned in the clamping board and the clamping board is screwed down for fixing the sample, the operation is simple and convenient and the clamping process can be performed quickly. Information of modulus of elasticity, deformation before yield stress and compression strength can be provided under a situation that non-metal materials are close to the experimental conditions for a compression test of carbon cloth prepreg.
Description
Technical field
The utility model relates to a kind of small-sized composite test anchor clamps of testing the nonmetallic materials compression performance.As the compression strenght performance index of compound substance, carbon cloth prepreg compression test.
Background technology
Being applied to nonmetallic materials compression performance test, will be the anchor clamps of axial force with loading usually, and in 1:1000, by two parallel to each other and load with axially vertical end face, the test function is stably controlled the crossbeam translational speed, and possesses following condition:
(1) drive member can stably be controlled the crossbeam translational speed, and this speed is relevant with the gripping object base material;
(2) the power value indication-power value indicating member force of compression that can intactly show sample and born, this member answers noninertia to lag behind under command speed, and the precision that shows of power value should its full test power value ± 1% in;
(3) compression extensometer precision should meet the requirements.
Prior art is with the anchor clamps of general connecting cleat and pedestal fixed clamp sample, and screw is yielding.After these anchor clamps use a period of time, when doing compression test, between last push-down head and test specimen end face, there is very big friction force, can changes fracture mode, influence test findings.
The utility model content
Task of the present utility model provides a kind of easy to use, and the clamping sample is quick, does not influence the test fixture of test findings.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of nonmetal compression performance test fixture, comprise, the clamping plate of pedestal and clamping sample, it is characterized in that, be shaped on two plane orthogonal L type steps on the pedestal, being used for the clamping plate of clamping sample is tightened in by bolt on the vertical plane of pedestal step, and the locating piece that guarantees sample clamping centering is housed in a side of pedestal.
Also twist the intrinsic cushion block that can change according to the length scale of sample on the horizontal plane of described pedestal step.
The utlity model has following beneficial effect.
The utility model connects clamping sample clamping plate by bolt, and sample is contained in the clamping plate, uses fixedly sample of screw-driving clamping plate, and is easy to use.Can guarantee the locating piece of sample clamping centering by the pedestal side, be convenient to the quick-clamping of sample, the sample clamping is quick.For the compression test of carbon cloth prepreg provide nonmetallic materials under state near test condition, comprise elastic modulus, the distortion before the yield point, the compression performance information of compression strenght.
Description of drawings
Below, the present invention is further described in conjunction with the accompanying drawings and embodiments.
Fig. 1 is the front view of the utility model compression performance test fixture.
Fig. 2 is the side view of figure.
Fig. 3 is the vertical view of clamping plate wherein among Fig. 1.
In the accompanying drawing: 1 pedestal, 2 cushion blocks, 3 clamping plate, 4,5 locating pieces, 6 bolts, 7 flat-top profiles of tooth, 8 screws.
Embodiment
Consult Fig. 1～Fig. 3, rise on the pedestal 1 of balance and fixation and be shaped on two plane orthogonal L type steps, pedestal about in the of 1 both ends of the surface be parallel to each other.Being used for the clamping plate 3 of clamping sample is tightened on the vertical plane of pedestal step by bolt 6.On the horizontal plane of pedestal step, twist the intrinsic cushion block 2 that can change according to the length scale of sample by screw 8.On a pair of clamping plate 3 of clamping sample have four with pedestal 1 on the consistent fastener hole in position, hole, bolt 6 is tightened clamping plate 3 by fastener hole.Sample holder makes 3 pairs of centers of sample major axis and anchor clamps strap between two end faces of clamping plate 3, and guarantees that the end face of sample end face and anchor clamps is parallel.For guaranteeing that sample is subjected to the stressed even of axial compressive force on testing machine, clamping plate 3 clamping sample site are shaped on flat-top profile of tooth 7 shown in Figure 3, and this flat-top profile of tooth 7 is vertically extended along the fore-and-aft plane of clamping plate 3, and sample is not formed destruction and can clamp sample.In a side of pedestal 1 locating piece 5 that guarantees sample clamping centering is housed, by the side that is fixed on pedestal with bolt 6.Assemble pin in other two holes, pin length should be determined according to specimen width.Locating piece 5 is to be convenient to the sample quick-clamping, guarantees the element of sample clamping centering.
During use, adjust the crossbeam of testing machine, until the strap 3 that just contacts anchor clamps.Sample is placed in the stand, makes it to flush with pedestal and center.Screw or bolt on the stand are tightened.The anchor clamps that install sample are placed on above the push-down head of testing machine.After the sample clamping is good, be placed directly on the testing machine push-down head, lean on the mobile drive seaming chuck of crossbeam that sample is applied axial loading force, test.
Claims (3)
1. nonmetal compression performance test fixture, comprise, the clamping plate of pedestal and clamping sample, it is characterized in that, be shaped on two plane orthogonal L type steps on the pedestal, being used for the clamping plate of clamping sample is tightened in by bolt on the vertical plane of pedestal step, and the locating piece that guarantees sample clamping centering is housed in a side of pedestal.
2. nonmetal compression performance test fixture as claimed in claim 1 is characterized in that, also twists the intrinsic cushion block of changing according to the length scale of sample on the horizontal plane of described pedestal step.
